Components of a main part of the house, such as the main frame, the floor cover plate, the top cover plate and the enclosed wall are prefabricated except for a basic part of the house, and thus industrial production is realized. Construction of the house is implemented by industrially produced components and products and processes such as field installation, connection, modification and so on. At the time a base of the house is constructed, factory production of various house component is performed. After the base is constructed, the main frame, the floor cover plate, the top cover plate and the enclosed wall are installed. The invention reduces a great deal of field work, and storey structure and external wall construction do not need a large amount of support frames and scaffolds, which saves energy consumption, water consumption, construction land and construction materials, and reduces construction noise and dust and construction time. Standardization and integration of house components and products are beneficial for application of new technology and materials and renewable energy such as solar energy. For example, solar devices are disposed on roofs, balconies and sunny sides of wall, or outside the structure layer, and the house is capable of improving residence comfort and increasing available use area, reducing consumption of energy and water, and thus facilitating a green house and green construction. Moreover, the invention is capable of implementing standardization, serialization and finalization, house drawing libraries, performing house design via digital management, and presenting architectural styles and aesthetic perception via design techniques such as difference of house layout, modeling of balconies, materials of decorative surface, color configuration and so on.

The main frame of the invention may employ a steel frame since steel is a renewable material that features good technical performance and ductility and capable of improving structural bearing capacity and seismic performance. Various steel components are easy for large-scale production, and feature high production efficiency and high product quality in manufacturing. With increasing demand for steel, to construct houses with steel is a development trend.

The floor cover plate and the top cover plate are light-weight laminated slabs. The light-weight laminated slab uses a hollow stripe board made of prefabricated and reinforced light aggregate concrete as a substrate to replace a traditional process of laying wooden formworks for a floor cover plate and a top cover plate made of cast-in-situ concrete. The substrate is disposed on a special tool-typed support frame to replace a support headframe. A reinforced skeleton tablet is disposed between the substrates, a reinforced net is disposed on an upper surface of the substrate, and the reinforced skeleton tablet and the reinforced net are casted via C30-grade fine-stone concrete to form the light-weight laminated slab. Since the hollow stripe board can be directly disposed on a main frame that is already constructed via the tool-typed support frame, the number of bottom formworks and supports is reduced, which improves production efficiency, reduces effect to surrounding environment, and overcomes limitation of storey-by-storey construction. After the main frame is constructed, construction can be performed from any storey upwardly or downwardly, or from multiple stories simultaneously whereby reducing construction time. After the light-weight laminated slab is formed, the only wet construction process - filed concrete casting is performed. After consolidation, the light-weight laminated slab is firmly combined with the main frame to form a combined structure interacted by a composite concrete floor cover or top cover and the main frame and bearing different acting force of the house. Construction of the light-weight laminated slab does not need to dismount a top bracing, a form spacer and a hoisting machine, and decreases some dominant processes. Moreover, the hollow stripe board, the reinforced skeleton tablet and the reinforced net can be directly processed in factories based on standards and transmitted to a construction field for installation, which greatly improves production efficiency, reduces construction time and helps to implement industrialization of manufacturing.

The integral composite prefabricated external wallboard of the invention comprises a structure layer, a light-weight filling block, and a heat insulation layer. The structure layer is a reinforced (the reinforced skeleton tablet and the reinforced net) concrete layer in the shape of a rib, and disposed on an outer side and surrounding of a wall board, and in a gap of the light-weight filling block, which makes the structure layer capable of bearing external force, climate change and rain erosion.

In factories, materials with good heat insulation performance and light weight, and post-casting, high-strength, waterproof and fine-stone concrete of the reinforced net are casted with doors and windows to form an integral external wallboard. After inside and outside decoration, the integral external wallboard is transmitted to the field for installation, which replaces traditional processes such as installing scaffolds, house walls, decorating and so on. The integral composite prefabricated external wallboards can be installed sequentially and upwardly with the main frame or on different stories simultaneously after the main frame is constructed. A supporting plate is disposed on a supporting point of the main frame, multiple positioning holes are disposed on the external wallboard are aligned with positioning pins disposed on the supporting plate, which makes it easy for adjacent integral composite prefabricated external wallboards to be positioned. After positioning, high-strength bolts are used for tightening and fixing via optimized fastening force, and a damping pad is disposed in a gap between the integral composite prefabricated external wallboard and the main frame. Pressure is generated after the bolt is tightened, under the action of the pressure, the damping pad is worn and deformed, and therefore is capable of implementing a seismic and energy dissipation effect, reducing force applied by an earthquake to the house, and improving seismic performance of the house. Integral composite prefabricated external wallboards on different stories are clutch connected, which is beneficial for stabilization and firmness of installation of the external wallboard. Ends of integral composite prefabricated external wallboards on the same storey are parallel connected. Connection between integral composite prefabricated external wallboards on different stories and that on the same storey are caulk sealed to improve a sealing effect. A pair of vertical slots is disposed on both ends of the connection between integral composite prefabricated external wallboards on the same storey and form a cavity, which increases space of caulk sealing, guarantees tight connection between the integral composite prefabricated external wallboards, facilitates a rain-proof and anti-seepage effect, and keeps warm and prevents colds. A joint between the integral composite prefabricated external wallboards is disposed on the main frame, which helps to perform caulk sealing of the integral composite prefabricated external wallboards and ensures connecting quality.

The integral composite prefabricated external wallboard is an integral external wallboard made based on a dimension of one room, namely one integral composite prefabricated external wallboard is an external wall of one room. The reinforced concrete is C30-grade and has a seepage-resistant grade of P6. The light-weight filling block is light-weight-material prefabricated plate with a bulk density less or equal to 500 kg/m² with certain strength. The light-weight filling block is dispose on an inner side of the integral composite prefabricated external wallboard whereby reducing an overall weight of the external wallboard and insulating (absorbing) sound. A squeezed foam board has a very low heat transfer coefficient, and is disposed on a middle portion of the integral composite prefabricated external wallboard as a heat insulation layer and operates as a heat insulation material for the wall. An external-wall door and a window frame are disposed in a mould before concrete is casted, so that the door and the window frame are firmly disposed in the wall, which improves weatherability of the door and the window frame. The invention can facilitate construction of the external wall of the house by transferring the integral composite prefabricated external wallboard to the field and perform installation one by one and caulk sealing, which decreases construction time, greatly reduces work amount of field construction, construction cost, and effect of construction land to the environment, increases the number of renewable materials, and facilitates real industrialization.

Except for industrialization of the main part of the house, standardization and industrialization of indoor bathrooms and stairs are also implemented. The bathrooms are configured to have several styles, sanitary wares are selected and molded in an integral or a combined form via polyester composites with pipe joints and connectors being reserved, and processes such as production of the wall, the sanitary wares and other accessories, decorative processing and so on are implemented in factories. Then, they are transmitted to the field for installation and connected to the reserved pipe joint, whereby facilitating convenient construction of the bathrooms, reliable quality and reduced construction cost.

The main frame employs a steel frame that is mature, safe and reliable, makes it convenient for industrialization, large-scale production and recycling use of resources, reduces weight of an upper portion of the house, features comparatively large ductility, a good seismic performance and convenient field installation and construction.

Test on the House of the Invention

1. Structure Loading Test on the Floor Cover Plate Made by the Light-Weight Laminated Slab

The loading test aims at testing stress of relevant positions of the floor cover structure (containing the steel beam of the floor cover) under the action of loading, and deforming and crack development of the structure part. The test is conducted by Shenzhen Institute of House Research Co., Ltd, and test report is also written thereby.

Test basis: Standard Methods for Testing of Concrete Structures (China national standard GB50152-92)

The floor cover plate employs a bi-directional plate (bi-directional forced) with a span of 4 m×4.5 m, and a unidirectional plate (unidirectional forced) with a span of 2.5 m. The loading test is conducted for two times, the first loading test comprises a scenario where stress of surrounding supporting steel beams varies as the floor cover made of laminated slabs is constructed, loading is stopped as a load value of the unidirectional plate is twice than a designed standard load value. Mid-span deflection of the plate is only 0.84 mm (L_(o)/2976), mid-span stress of a plate rib is 32^(N)/mm², and negative reinforcement stress of a support is 54^(N)/mm².

As a load value of the bidirectional late is 4.2 times than a designed standard load value and a first crack appears, loading is stopped. Short mid-span deflection of the plate is 4.32 mm (L_(o)/926), and long mid-span deflection of the plate is 6.35 mm (L_(o)/710).

Central Reinforced Stress:

-   -   short mid-span stress of a plate rib 61^(N)/mm²     -   long mid-span stress of a plate rib 52^(N)/mm²     -   short negative reinforcement of a support 54^(N)/mm²     -   long negative reinforcement of a support 32.4^(N)/mm²

To demonstrate bearing capability of the light-weight laminated plate to be damaged, another damage load test is conducted.

A unidirectional plate: load value thereof is 7.5 times than a designed standard load (namely 35 KN/m²), the maximum mid-span deflection is 6.4 mm (L_(o)/390), since loading blocks are highly piled, it is impossible to load any more.

A bi-directional plate: load value thereof is 13 times than a designed standard load (namely 32.5 KN/m²), the mid-span deflection is 12.85 mm (L_(o)/311), and a width of the crack at the bottom of the plate is 1.5 mm. At this time the floor cover plate is regarded as entering a plastic deforming phase. The test indicates the floor cover plate made of the light-weight laminated slab has high bearing capacitance and enough safety reservation.

2. Heat Resistance Test on the Integral Composite Prefabricated External Wallboard

The loading test and heat resistance test are conducted by Shenzhen Institute of House Research Co., Ltd, and test report is also written thereby. The test is based on China national standard GB/T13475-92 named “House Element-Determination of Steady-state Thermal Transmission Properties-Calibrated and guarded hot box”. A test equipment employs a BW-1212WT-type stable heat transmission test system JN002.

Test condition: air temperature in the hot box is 35° C., air temperature in the cool box is −10° C. Air flow rate in the hot box is natural convection, and air flow rate in the cool box is 3 m/s. Heat transmission direction of samples is from warm to cool. Airflow direction in the cool box is upward. Emissivity on inner surface of the box is 0.85. The samples' state is natural drying.

By comparison of heat resistance, materials such as the light-weight-material prefabricated plate, the squeezed form plate and so on are selected as materials having heat insulation effect in the laminated external wallboard. The reinforced net is casted via C30-grade fine-stone concrete and post-casted in an embedded form. After the heat resistance test, a thermal conductivity is 1.05 W/m·K, which is less than an index of 1.5 W/m·K defined by the Power-saving Standard for thermal conductivity of wall.
